feat(android): partial-album detail gets Play/Shuffle + track 3-dot menu

You can still enjoy an incomplete album: the downloaded-tracks section now has
Abspielen + Zufall buttons (play/shuffle the downloaded songs) and each
downloaded row gets the 3-dot context menu, threaded from both artist screens.

 - **Android (lyrics)** — Synced-lyrics auto-scroll is **not smooth**: it follows playback and highlights the right line, but the list jumps to it rather than gliding. Web autoscroll is smooth. Not yet fixed.
